Description

From the 3 D-printing system and method for the biomaterial from esculent swift edible bird's nest

Technical field

The present invention relates to 3 D-printing (3D) system and method for biology or biologic material, and in particular, it is related to The printing of nanostructured biomaterial from esculent swift edible bird's nest.

Background technology

In the past ten years, three-dimensional (3D) printing is from developing archetype to end user's product, big rule Mould customizes and the production of complex parts.Three-dimensional (3D) printing, the particularly business application of the 3D printing of plastics or high molecular material Just become to become more and more popular and generally.Now, there are many plastics or polymer material 3D printing tool can be used, such as welcome " Makerbot ", sprays polymer in a manner of successively, until completing complicated 3D products.

However, the application of the 3D printing of food or biomaterial is not common, the particularly application of valuable biomaterial, This is a quite undeveloped field.Biomaterial or biology derived material are derived from the material of living organism.It is most of Such material contains carbon and can rot.The example of biomaterial be timber, malthoid, straw, humus, fertilizer, bark, Cotton, spider silk, chitin, fibrin, bone and esculent swift edible bird's nest.

The 3D printing of biological product is using more much more complex than typical plastics or high molecular material, each biomaterial is all Have oneself unique and unique a set of biology, physics and a chemical characteristic, and each unique biomaterial be required for it is a set of Very special 3D printing system and Method of printing, to deliver successfully or the printing effect of good quality and high yield.

Some biomaterials are very expensive materials, particularly esculent swift edible bird's nest.Esculent swift is to include gold Birds in silk swallow category, waterfall Apus, precious Apus and the category of dwarf's aerodramus four.Aerodramus is particularly eye-catching, because It obtains the use of echolocation and the saliva nest of its complicated structure, without other species in certain species, such as feather, moss Or branch.Java esculent swift is the bird of a swift race found in Southeast Asia.

" edible bird's nest " word used in this specification includes the bird's nest made of esculent swift ptysis.Especially by The edible bird's nest that Java aerodramus esculent swift is built.Original esculent swift bird's nest includes dry saliva and/or mixing bird The saliva of the drying of feather.

Esculent swift edible bird's nest or for " bird's nest " be one of Chinese medicine (TCM) ingredient being of great rarity.From before 100 years The purpose that Chinese are used to improve health eats this TCM ingredients.Traditionally, the esculent swift edible bird's nest is from cave Harvest, then cleaning, molding and drying.In general, dry bird's nest or " bird's nest " are doubly boiled with syrup, and with liquid or half Liquid form is eaten.

Typically, original esculent swift edible bird's nest will pass through the cumbersome cleaning process based on water for a long time, Ran Houjie Get off and slowly moulded and drying process and height is labour-intensive by a series of before consumer is sold to, to become Many different shapes and size.

In general, edible bird's nest is moulded or forming process is very time-consuming process, mainly due to the property of operation, The operation is that worker needs manually to arrange and match many length before they " bonnily " to be shaped to an ideal shape Short small edible bird's nest texture or band.Therefore, it is described mould or forming process need it is experienced and very skilled Worker delivers " bonnily " molded edible bird's nest.

In fact, three most important parameters for determining edible bird's nest price fixing are their shape, quality and big It is small.The main object of the present invention is to overcome the processing challenge of edible bird's nest, to deliver best shape, quality and size, especially Be mould in improvement, be molded and texture/band alignment processes in.
